摘要
The objective of this study is to determine the effect of emollients in a propanol-based hand rub on skin dryness and erythema. In this prospective, randomized, controlled, doubleblind trial, 35 subjects participated; of them approximately half were atopic (modified Erlanger atopy score ≥ 8). 2 propanolbased formulations were tested in a repeated open application test, 1 contained a mixture of emollients (0.81% , w/w). 2 aliquots of 0.7 ml of each formulation were applied twice per day over 2 weeks to the cubital fossa of each subject after random assignment of the preparations. Treatment areas were assessed before each application and 3 days postfinal application by visual inspection for erythema and dryness according to a standard scale. The sum score over all assessment timepoints served as primary parameter. The mean sum score for erythema and dryness was significantly lower for the hand rub with emollients (0.8 ± 2.4) in comparison with that for the hand rub without emollients (1.5 ± 3.5; P = 0.022; Wilcoxon signed rank test). A comparison of the atopic and non-atopic subjects revealed no significant difference for any of the products (P > 0.05; Mann-Whitney U test). It is concluded that the addition of emollients to a propanol-based hand rub can significantly decrease irritant contact dermatitis under frequent-use conditions.
